Abstract
Perturbative corrections of the order of alpha(s) to inclusive double
differential lepton distribution from b quark decay are considered. A
perturbative correction to the charged lepton energy spectrum has been
calculated for an arbitrary charged lepton mass. The perturbative con
tribution suppresses the partial rate but almost does not change the s
hape of energy distribution. Applications of our result to semileptoni
c B meson decays are briefly discussed.
